ROTOGRIPPERCOMBINATIONSSELECTIONTo select the proper RotoGrippercombination, each component ofthe RotoGripper (the <strong>rotary</strong> actuator aswell as the gripper) must be sizedindividually according to theapplication requirements.1. GRIPPER SELECTIONWhen choosing a gripper, refer to theselection information beginning on page5 of the gripper section in this catalog.Select the appropriate angular orparallel gripper size <strong>and</strong> jaw styleaccording to the load requirements ofthe application <strong>and</strong> consider the safetyfactor values as well.2.ROTARY ACTUATORSELECTIONRefer to pages 20-21 of the <strong>rack</strong> <strong>and</strong><strong>pinion</strong> <strong>rotary</strong> actuator section forselection specifications.Select a <strong>rotary</strong> actuator bore sizeaccording to its torque requirements,bearing load capacities <strong>and</strong> considerany options if required.IMPORTANT NOTE: Calculate therotational mass moment of inertia (J m)if the <strong>rotary</strong> actuator will physicallystop the load.Then, calculate the Kinetic Energy perstop <strong>and</strong> determine if st<strong>and</strong>ardadjustable stops with bumpers,cushions or shock absorbers will berequired.3.SELECT THEROTOGRIPPERCOMBINATIONWhen selection of the gripper <strong>and</strong><strong>rotary</strong> actuator components arecomplete, select which RotoGrippercombination (a drive-from-behind or adrive-in-front ) is desirable for theapplication.Drive-From-Behind CombinationsThe table shown below lists thepossible Drive-From-Behindcombinations that are available. Referto pages 38 <strong>and</strong> 39 of the orderingsection for configurating theappropriate model.ROTARY ACTUATORRA075RA100RA100RA125GRIPPERGPA063GPP063GPA063GPP063GPA100GPP100GPA100GPP100NOTE: Both angular jaw styles of finger (JS1)<strong>and</strong> flush (JS2) are available in RotoGrippercombinations.Drive-In-Front CombinationsDrive-In-Front combinations combineTol-O-Matic st<strong>and</strong>ard <strong>rack</strong> <strong>and</strong> <strong>pinion</strong><strong>rotary</strong> <strong>actuators</strong> <strong>and</strong> <strong>grippers</strong> togetherutilizing coupler kits.The table below lists the possible <strong>rotary</strong>actuator <strong>and</strong> gripper combinations forDrive-In-Front styles. Refer to page 30for coupling kit specifications, partnumbers <strong>and</strong> ordering procedures.ROTARY ACTUATORRA075RA100RA125GRIPPERGPA038GPP038GPA063GPP063GPA063GPP063GPA100GPP100GPA100GPP100GPA150GPP150NOTE: Both angular jaw styles of finger (JS1)<strong>and</strong> flush (JS2) are available in RotoGrippercombinations.25
